IMPROVEMENT IN AXLE-BOXES FOR VEHICLEWHEELS.

Specification describing a certain Improvement in Axle-Boxes, inventedby DAVID DAL- ZELL, of South Egremont, in the county of Berkshire andState of Massachusetts.

This invention relates to an axle-box whose head is composed of rings ofdifferent thicknesses, asmany in number as the sections of differentdiameters in the bore of the box, said rings being bound together bytie-pieces inserted in grooves running crosswise of the rings atopposite sides of the head, and projecting beyond the inner end of thehead far enough to embrace the inner end of the box and form the carswhich prevent the box from turning in the hub.

Figure l is a perspective View of the box, rings, and tie-pieces, allseparate; and Fig. 2 is a transverse vertical section of the same puttogether. i

A is the box aforesaid, the same being composed of a suitable piece ofpipe. The head B is made up, in this instance, of three separate ringsof different thicknesses, a b c. I do not, however, limit myself to anyparticular number of rings. It is only necessary that there should be asmany as there are sections of different diameters in the bore of thehead, because, by using rings, these sections are formed Without thelabor of turning out the inside of Specification forming part of LettersPatent No. 128,861, dated July 9, 1872.

the head. The middle rin g has thelargest bore, so as to form a groovein the inside of the box to contain oil for lubricating the axle-arm.The rings are punched by machinery and formed with dovetail grooves ofthe same dimensions running crosswise of their opposite sides, in whichgrooves are inserted tie-pieces d, which bind the rings together, and,projecting past one end of the head B, form the ears 0, between, andtouching, which the inner extremity of the box A is placed, the sameabutting againt the side of the ring a. The box, rings, and tiepiecesare then brought to a suitable degree of heat, and then subjected, byany sufficient means, to a pressure powerful enough to combine them asin a solid piece, by butt-welding, in a very expeditious and perfectmanner. The article is-then ready for finishing and tempering to aproper degree of hardness.

I claim as my invention--- 1 i The head B made of rings of differentthicknesses, arranged so as to form a groove in the inside of the headto contain a lubricant, and combined with the tie-pieces d, ears 0, andbox A, substantially as specified.
